摘要: Atrial arrhythmias lower the biventricular pacing percentage in cardiac resynchronization therapy (CRT) treated patients (pts) and have a high prevalence this population. External electrical cardioversion (ECV) is commonly performed to restore sinus rhythm. There paucity of data on safety efficacy ECV pts with CRT devices. Forty-three devices undergoing at two centers were included prospectively. Devices interrogated immediately prior after ECV, as well 4 weeks. (CRT-D 38 CRT-P 5) all implanted left pectoral position, predominantly bipolar ventricular (LV) leads. Sixty-one shocks delivered, biphasic. Arrhythmia had recurred 36 % follow-up (FU). was significant increase LV lead threshold voltage drop impedance which returned normal FU. An least twofold FU seen 2 leads 0.5 V 3 Overall, significantly increased during safe effective two-center study. A transient observed. Relevant changes occurred five leads—identification regular these are necessary. Restoring SR through but arrhythmia recurrence frequent. atrial require close ECV.
